From Peabody Award-winning producer Lea Thau, "Strangers" features real people telling true stories from their lives, sponsored by KCRW in Los Angeles and part of PRX's Radiotopia network. Lea was the Executive & Creative Director of the storytelling organization The Moth for 10 years and she created The Moth Podcast and The Moth Radio Hour. Ranging from the hilarious to the heartbreaking, each episode offers a unique take on the theme of "strangers"--the strangers we meet, the strangers we sometimes become, and the strange places we go. It's about travelers, seekers, dreamers, lovers and warriors. It's about fateful moments, bad dates, long lost friends, life-saving kindnesses, and those frightful moments when we discover that WE aren't even who we thought we were.
